Which oops concept is used in php?
PHP is a server-side scripting language, mainly used for web development but also used as a general-purpose programming language. Object-Oriented Programming (PHP OOP), is a type of programming language principle added to php5, that helps in building complex, reusable web applications. Show In this blog, we will be explaining some of the Object-Oriented Programming concepts in PHP with some examples. The PHP Object-Oriented Programming concepts are:
Class & Object:
Example for simple class: Output: In the basics of object-oriented, let see how to define a class and create an object: Creating Objects in PHP Calling Member
Function Output for the above code Samsung S8 Inheritance When the properties and the methods of the parent class are accessed by the child class, we call the concept has inheritance. The child class can inherit the parent method and give own method implementation, this property is called overridden method. When the same method of the parent class is inherited we call as inherited method. Now let us see types of inheritance supported in Object Oriented Programming and corresponding Php inheritance examples. Types Of Inheritance
Single Level Inheritance: In Single Level Inheritance the Parent class methods will be extended by the child class. All the methods can be inherited.
Example for Single Level Inheritance Output MultiLevel Inheritance : In MultiLevel Inheritance, the parent class method will be inherited by child class and again subclass will inherit the child class method. Output Class A is 80 INTERFACES:
Rules of Interfaces:
Example for the interface class Output: 2) Interface can be extended with another interface using extends keyword Output: Note on Interfaces:-
Abstract Classes:
Example for Abstract class
Notes on Abstract classes:
Now Let us see the difference between abstract class and interface.
In the end, now we are able to create a class, define objects for the class and create methods. We also learned about different topics of object-oriented like inheritance, interface, abstraction. The basic concepts of OOP is explained in this blog.

Object-oriented programming is a programming style that refers to the association of various components and revolves around the inheritance, polymorphism, encapsulation, and abstraction concepts.
Does PHP have OOPs?Yes, the latest versions of PHP are object oriented. That is, you can write classes yourself, use inheritance, and where appropriate, the built in functionality is built in objects too (like MySQL features).
Which OOPs concept is used?Object-Oriented Programming System (OOPs) is a programming concept that works on the principles of abstraction, encapsulation, inheritance, and polymorphism. It allows users to create objects they want and create methods to handle those objects.
Does PHP support polymorphism?Generally, it is of two types: compile-time (overloading) and run time (overriding), but polymorphism in PHP does not support overloading, or in other words, compile-time polymorphism.
